Thanks for feedback
I will keep in mind
Just came to my mind,
if only WinPcap required for another application,
(of if you can't find portable version of an application)
check google for:
winpcap unattended install
writing a simple .cmd would to the trick
This method is also valid for most applications
Only bad side, it will use free space on X: , so don't do this "unattended install" trick with big applications
